POSITIONING

• Place the appliance on a stable, dry base
and make sure that no dust from the base is
sucked by the fan.
• The generator must be placed far from the
trajectory of any particles released from mil-
ling operations.
• The generator must be placed at least 20
cm away from any obstacles (including walls)
so as not to limit the efficiency of the fan.
• The room temperature during work must re-
main between -10 and +40°C.
• Protect the machine against heavy rain and
direct exposure to sunlight.
Warning: Machine stability is ensured
for a maximum inclination of 15°.

CONNECTION TO THE POWER MAINS

The good functioning of the generator is en-
sured by its proper electric connection to the
power mains, which must be carried out by
experienced personnel and fully respecting
the current regulations regarding the installa-
tion of industrial electric appliances.
For relevant information regarding the cha-
racteristics required for the power distribution
system, please read the relative paragraph in
this document.
The supply voltage of these generators is
110/230Vac +/-10% – 1Ph
power grid corresponds to these values and
is calibrated according to the maximum con-
sumption of the generators (please see the
tables with technical information), simply
connect the power cable to a bi-pole plug +
ground of suitable capacity and insert it in the
mains socket.
• Do not use the current generators with ca-
ble extensions exceeding 25 meters and with
less than 4 mm² of diameter.
• The power cable must not be allowed to coil
or tangle. It must remain away from sources
of heat, oil, and solvents and protected from
crushing (risk of electric shock).
• The power cable contains power voltage
(110/230 Vac); it therefore must be periodi-
cally inspected and replaced when deteriora-
ted.
Warning: The yellow/green cable must
be fixed to the earth pin. In case of power
cable ruptures this has to be the last one
to yield. This will ensure that the genera-
tor is grounded.

The protection gas of the electric arc on these
generators is only used during welding with
infusible electrode (TIG). It is not required du-
ring welding with coated electrodes (MMA).
• Do not forget to slightly open and then close
the tap of the cylinder to eliminate any impu-
rities.
• Assemble the pressure regulator on the
cylinder, after making sure that the gas flow
regulation knob is loose.
• Make sure the connector is tightened before
opening the cylinder tap.
• Assemble the connection on the gas tube of
the generator and the gas tube to the exit of
the pressure regulator.
• Slowly open the cylinder tap. During wel-
ding, gas flow is a function of the parameters
and accessories of the welding. The regula-
tion range is normally between 5 and 15 liters
per meter.
Note: Additional information on how to work
safely with gas, please carefully read the
PROTECTION GAS paragraph of this docu-
ment.

• Connect the foot pedal 12 pin plug to the
front panel of the machine into socket 7.
• As soon as plug is connected, the remote
control is automatically activated on the pe-
dal, the machine can work only in 2T mode.
The arc striking is done pressing on the pe-
dal. Current adjustment is done using the pe-
dal, from its minimum value to Iw that was
preset on the front panel before activating the
remote control.

WELDING GAS CONNECTION

Warning: The gas cylinder must be fixed
in place with a safety belt.
